Cage is a custom cage built by Fall-Line - Nobody builds them better and safer. There are pictures of the cage in the ad. There is also a description of the cage in the ad- Fall-line custom chromoly 1 ¾ tig welded roll cage with subframe and strut tower reinforcement. Fully gusseted A- and B- pillars

It does have an adjustable brake bias.

It also has a fully integrated traction control system that is regulated by the Motec dash.

Here is the dyno graph, but note that this run was prior to installing a new custom thermal coated exhaust and the ram-air intake. I would estimate that the addition of the new exhaust and intake system yields an additional 15-20 hp at the rear wheels.
